Packages are being stored in the specified folder but I can only install and manage a package in a single solution. For example, using the above structure, I install a package using the package manager while working with SolutionA. I want to install the same
package in SolutionB, but when I view the package manager while in SolutionB I get a "Package already installed" message and there seems to be no way to actually install the package.

Is it possible to have a single location to store packages but then install them in multiple solutions?
